How to Find a Facebook Page ID From a Vanity URL

The short version: your Page ID is the long number string behind your friendly facebook.com/yourbrand URL, and you can pull it in under a minute using the page's "About" details, the page source code, or a free lookup tool, no developer required. You need it for ad campaigns, Messenger integrations, and most third-party marketing tools, because Facebook's systems run on numbers, not names. I'll show you four ways to get it, which one to trust, and why the method most tutorials recommend first is the one that breaks most often.

Why your vanity URL isn't enough

When you set up a Facebook Page, you get a pretty web address like facebook.com/yourbusinessname. That's the vanity URL. It's for humans. Behind it sits a Page ID, a string of digits (sometimes 10 numbers, sometimes 15 or more for newer pages) that Facebook's systems use to identify the page.

Most marketing tools don't care what your page is called. They care about that number. So the moment you try to connect a plugin, set up a Messenger bot, build a custom audience in Ads Manager, or install a Facebook comments widget on your website, you'll hit a field asking for your Page ID, not your page name. If you've only ever used your vanity URL, this is where things stall.

I've seen people spend an hour troubleshooting a broken WordPress Facebook plugin, convinced it's a coding issue, when the real problem is they typed "yourbusinessname" into a field that wanted "114823049192837". It's a small thing. It stops entire setups dead.

Method 1: the About page (fastest, works for most pages)

This is the one I'd try first, not because it's the one everyone recommends, but because it works for the widest range of page types:

• Go to your Facebook Page
• Click "About" in the left-hand menu (on desktop)
• Scroll down to "More info" or "Page transparency"
• Look for "Page ID", listed as a plain number

If you manage the page, you can also go through Meta Business Suite: click Settings, then Page Details, and the ID is listed there alongside your category and creation date.

Method 2: view page source (the one that's quietly unreliable)

This is the method almost every tutorial puts first, and it's the one I'd put last. Here's how it works when it does work: right-click anywhere on the page, choose "View Page Source," then use Ctrl+F (or Cmd+F on Mac) to search for "pageID" or "entity_id". You'll usually find a string of numbers near the top of the code.

The problem: Facebook changes its front-end code often, and the page source method depends on finding the right variable name in a sea of minified JavaScript. On some pages it's "pageID", on others it's buried inside a JSON object labelled something else entirely. I don't think it's wrong to mention this method, but I do think it's dishonest to present it as reliable when it depends on Facebook not having shipped an update that week.

Method 3: the free lookup tool trick

If you just want the number without digging through code, paste your full vanity URL (for example, facebook.com/yourbusinessname) into a free Facebook Page ID finder tool. There are several reputable ones, run by social media management companies as lead magnets. Type in the URL, hit search, and the number appears instantly.

This is the method I'd recommend to anyone who isn't comfortable with browser dev tools. It's quick, it doesn't require you to manage the page, and it works even on pages you don't own, which matters if you're researching competitors or vetting an influencer before a partnership.

Method 4: the Graph API Explorer (for anyone comfortable with a bit of setup)

If you're building something more technical, like a custom integration or a reporting dashboard, use Meta's Graph API Explorer directly. Log in with your Facebook developer account, select your app, and query the page's vanity name (for example, "yourbusinessname?fields=id,name"). The response comes back as JSON with the ID clearly labelled. This is overkill for a one-off lookup but it's the right tool if you're pulling Page IDs programmatically for dozens of pages at once, which is common if you run social media for a roster of clients.

Worked example

Say you run a small bakery with a Facebook page at facebook.com/rosiesbakery. You want to launch a Facebook ad targeting people who've engaged with your page in the last 90 days, a classic warm-audience retargeting move. Ads Manager asks you to connect your "Facebook Page" by ID, not by name, when you're setting up a custom audience source. You go to the About section, find "Page transparency," and spot the number: 103847562910384. You paste that into the audience source field, and suddenly your retargeting setup, which was stuck, moves forward. Total time: about ninety seconds, once you know where to look.

What the Page ID is used for

• Connecting Messenger bots or chat automation tools to your page
• Setting up custom audiences and retargeting in Ads Manager
• Embedding Facebook comment plugins or page like boxes on your website
• Pulling page insights data through third-party analytics tools
• Verifying a page's authenticity before working with an influencer or running co-marketing

That last one matters more than people think. If you're vetting a potential partner page before a paid collaboration, checking its Page ID (and how long it's been attached to that page) can tell you whether a page has changed ownership or been renamed, which is a useful signal if something about the account feels off. I'd pair this with checking the page's post history and, if you're assessing its commercial value, looking at how a page with a large following earns money before assuming follower count alone means credibility.

The uncomfortable bit nobody mentions

Your Page ID is not permanent in the way people assume. If a page gets merged with another (common when a business rebrands or consolidates multiple location pages into one), or if Facebook flags and reinstates a page after a suspension, the ID can change. I've seen business owners bake a Page ID into a custom-built website plugin, forget about it for two years, and then wonder why their embedded reviews widget silently stopped updating. The fix isn't exciting, it's just checking your Page ID again any time you've gone through a page merge, a rebrand, or changed your Facebook Page URL, because the vanity name and the ID aren't as permanently linked as most tutorials imply.

A quick troubleshooting checklist

• If "About" doesn't show a Page ID, check whether you're using the mobile app (switch to desktop or the mobile browser version instead)
• If a lookup tool returns "page not found," your vanity URL may have a typo, or the page's privacy settings are restricting public info access
• If the ID you find doesn't match what an ad platform expects, you may be looking at an Instagram-linked ID rather than the Facebook Page ID itself, which is a common mix-up when accounts are connected
• If you manage multiple pages, use Meta Business Suite's business settings rather than hunting through each page individually

Where this fits into your wider Facebook strategy

Finding your Page ID is a small technical task, but it tends to surface when you're doing bigger things, launching ad campaigns, setting up Messenger automation, or trying to grow a Facebook group organically and connect it to your page's audience data. If you're also running video content, the same ID is what some ad tools use when you want to advertise effectively using Facebook Reels, since the ad account needs to know exactly which page is the source of the content. And if you're trying to track who's watching your Reels before building a retargeting campaign off the back of it, it's worth knowing how to find a Facebook Reels viewer for your content first, so you're targeting the right audience once you've got your ID sorted.

If all of this feels like more fiddly setup than you have patience for, and you're trying to get Facebook ads, automation, and audience targeting working as part of a bigger AI-driven marketing push, it might be worth getting an AI consultant for your small business to sort the technical wiring once, rather than you patching it every few months.

Frequently asked questions

What does a Facebook Page ID look like?

It's a string of digits, typically 10 to 17 numbers long, with no letters or symbols, for example 103847562910384. It has nothing to do with your page name or vanity URL.

Can I find a competitor's Page ID without managing their page?

Yes. Paste their public vanity URL into any free Facebook Page ID lookup tool, or view their page source and search for "pageID" in the code. You don't need admin access for either method.

Does my Page ID change if I change my Facebook URL?

No, changing your vanity URL doesn't change your Page ID. However, the ID can change if your page is merged with another page or goes through a major account restructure, so it's worth re-checking after any of those events.

Why do ad tools ask for a Page ID instead of just the page name?

Page names can be duplicated, changed, or similar across multiple businesses, which makes them unreliable for software to match accurately. The ID is unique and permanent under normal circumstances, so platforms use it to avoid connecting the wrong account.
